如何创建与Android的光标数据的列表阵列 [英] How can I create a list Array with the cursor data in Android

问题描述

如何创建一个列表阵列（列表中显示第一字母时，滚动）用光标数据？

How can I create a list Array (the list display First Alphabet when scroll) with the cursor data?

推荐答案

通过每一个元素进去的光标，并逐个添加它们一到的ArrayList 。

Go through every element in the Cursor, and add them one by one to the ArrayList.

ArrayList<WhateverTypeYouWant> mArrayList = new ArrayList<WhateverTypeYouWant>();
for(mCursor.moveToFirst(); !mCursor.isAfterLast(); mCursor.moveToNext()) {
    // The Cursor is now set to the right position
    mArrayList.add(mCursor.getWhateverTypeYouWant(WHATEVER_COLUMN_INDEX_YOU_WANT));
}

（更换 WhateverTypeYouWant 与任何类型你想的的ArrayList 和 WHATEVER_COLUMN_INDEX_YOU_WANT 与您希望从游标来获取值的列索引。）

(replace WhateverTypeYouWant with whatever type you want to make a ArrayList of, and WHATEVER_COLUMN_INDEX_YOU_WANT with the column index of the value you want to get from the cursor.)
